$100 for a burger is a GREAT deal!
The Jet Room has good food and even better service, but the star of the show is the excellent view of the runways of MSN/KMSN - Dane County Regional Airport.
We signed ourselves for the $100 burger, which includes a 30 minute sight-seeing flight for two around Madison. The flight is provided by Wisconsin Aviation.
Our sandwiches were decent (not the best, but satisfying and filling) and the prices were reasonable. The staff was very friendly. However, the view of the runway is well worth every penny of the meal's price. We were able to watch the 115th's F-16s take off and land and see many other neat aircraft.
Call ahead for reservations, as this place is BUSY. We'll be back for breakfast.
